To find the surface area of a box, add the areas of the faces: 2(lw) + 2(lh) +2(wh). What is the surface area of the box below?

H=8m W=5m L =11m

My answer is 366m.

2(55) + 2(88) + 2(40)

MY ANSWER ABOVE IS 366m?

To find the surface area of a box, you need to find the areas of all six faces and then add them together.

For a rectangular box, there are three pairs of faces that have the same dimensions:
1. The top and bottom faces, with dimensions l x w
2. The front and back faces, with dimensions l x h
3. The left and right faces, with dimensions w x h

To find the area of each face, multiply the length (l) by the width (w), the length by the height (h), and the width by the height.

In this case, the given dimensions are:
H = 8m
W = 5m
L = 11m

So the surface area formula for this box would be:
2(lw) + 2(lh) + 2(wh)

= 2(5m x 11m) + 2(5m x 8m) + 2(11m x 8m)

Simplifying this expression, we have:
= 2(55m^2) + 2(40m^2) + 2(88m^2)

= 110m^2 + 80m^2 + 176m^2

= 366m^2

Therefore, the surface area of the given box is 366 square meters, not 366m as you mentioned.
